I got a wee bit of a laugh from the second animation. Most people I know are visual learners and having something that imparts a bit of humour to the lesson makes the lesson more memorable. At least to my mind. Thanks Rob for one of the best learning channels on KZfaq.

I liked the animation of the photograph very much. It added something to the explanation as it was also in context.

Love your informative videos, I'm amazed at how you can churn them out, inspiring, not crazy about animations, rather see mechanics.

I liked the animations; it was fun and added more entertainment to the video. I really love and appreciate all of the ideas and technologies that you share with us!

I'm okay without the 3D animation you're definitely entertaining enough and your occasional lab partner. Learning a lot from your videos and hopefully one day I save enough to get a good quality 3D printer.

I think instead of those animations, it would be really cool to see a time lapse is your design process

The animations are a bit of fun, so I have no objection to them. I'd never seen that flex ring idea before, so thanks for showing it.

Your info is what’s important. If you have fun adding animation to your vids go for it!

I love the voice over animation. Wisdom speaking from beyond the grave.

You’re not going to lose any viewers with the AI animations. We are here to discover and learn - to broaden our horizons. I thought it was quite entertaining to see and hear the long dead inventor of the drive give voice to his creation! Keep playing and experimenting with it!

I loved the animation it really helped with understanding what was going on.. 👍

Awesome video. Anything that helps get the point across.

Great Segment, Thanks. I had a couple of tiny motors on an old Cessna 337 that used harmonic wave reduction drives to open and close the engine cooling cowling flaps. When the drives wore out after a few years and the cost of replacement motors were about $4,000 each, I replaced them with industrial positioners for about $120 each. they functioned better and only added about 1lb. each and will likely last a lifetime. Every technology has its best application and miss-application I guess.

Thank you for the forever- great information vids!

Cute animation...but your content and good cheer stands alone always.

Sorry Robert the voice over animation is very distracting, its a no from me..

Ohh, I hope you gonna start talk about liqued piston new variant of Wankler motior! But thanks Rob. you just show how miracle good thing we easy can make now! /Mikael

I'd rather watch your talking head than an animated one, Rob :) That said, I love Veritasium's animated pieces (like the one on analog computers). Keep up the great work, your videos are almost always really enjoyable

Great video. And the animations were entertaining! But just to clarify in regard to the bearings: mil = 1/1000 inch, while millimeter, or mm, = 1/1000 meter

Loved the animations :)

Animations were mesmerizing. Thanks

I love the animations myself.. as well they are an example to anyone watching a way to use this technology that may which may spark an idea for it's use in a totally different subject that could spring board someones potential in ways that wouldn't have happened if you had not used it yourself... You are a wonderful influence and teacher for so many ppl Thank you 🐝

The other way of making this gear compounding system is to use 2 separate gear faces which allows you to use the same modulus but different gear diameters.

Those statements from such noted individuals was a great addition!

Hi Robert: I'm in Canada, but it was neat to hear you're in Canterbury. I have to say, I found it to be the coolest place we visited in England. Hooe to one day be back again. Have you looked at that KZfaq video by Hyundai, about their "UniWheel"? It'd be great to make one on a 3D Printer to experiment with. Your videos have inspired me to treat myself to one, probably on a Boxing Day sale, and most likely an Elegoo, Crealy, or Qidi. Cheers!

Fascinating animations…..it’s like a family of mice have moved into the face of a corpse 😂

Always something new in your videos. Love it. Duh, OF COURSE it's skater bearings LOL

Great Video Similar to what Leyland trucks used back in the day They had plantary hub reduction set ups Not high speed but they'd pull a train

I certainly wasn't expecting those talking heads, I thought it was a clip from a different video at first. I thought it was a fun gag, but I'd certainly not want a whole video like that because of all the energy your commentary brings to these videos.

Love the animation, really takes it up a gear. Love the videos.

I enjoyed the second individual, very nice. Makes me think that I'm on the Halo-deck on Startrek.

I have to be the tenth man... nope nope nope that was some creepy stuff... 🤣😂🤓🤓

Thank you for always providing entertaining and thorough projects. As you, and everyone else, have learned .. there are three camps of opinions: some love the animations, some hate them, and the rest have no care. Personally, the Musser part was a bit unsettling, whereas the graphic was entertaining for a 50-50 split. Always look forward to your posts. Ta!

That kind of animation usually just makes me uncomfortable due to the uncanny valley, lol

lol those AI animations creep me out. Great video as always!

TQ's latest mid drive for eMTB bikes uses these principles. Nearly invisible and coughs up 50Nm of continuous torque while sipping battery. Really good stuff.

The animations just spoke at a much slower speaking cadence than you do, and without your excellent brevity; so they really felt like they slowed the video down a ton. I’d recommend putting the text on screen while it is being read as well as speeding it up. Always be testin

I am going to try one of these out for a robot. It seems like it would go well with something like a nema 17 stepper motor, for a robot arm! Regarding the animations, I liked them. I've used that tool myself for creating short animations. If you are able to remove the background of the image first, so as to submit only the head and body of the character, the tool can do a better job of making the whole body animate - not just the head area.

Hey Rob!! I don't have the magnets for it at the moment but I think you'd be very interested in trying it out for yourself! If you have a Halbach array on a circular disk, you could use a flux coupling to be able to transfer much more torque with magnets than you can achieve normally. North amd South want to remain coupled, so you could have two of these in opposition separated by a plastic washer or something to prevent them from sticking. I could also see generator designs based off the Halbach array taking advantage of generation at the rim. Anyways! I just wanted to share this with you in case you were interested.

Loved the animation great fun

👍 On the animation.

Enjoyed the animation.

That's me not sleeping tonight...

Naw, You are animated enough just being yourself 🙂

Ooh! KZfaq gave me a warning before I could comment! This is now my comment. 🤓

The animation was good. I just think there is enough confusion about what is reality and what is not that I would put a note in the corner specifying when it is not reality or not real footage.

The animations was well within the uncanny valley.

Animations are awesome as long as it's not fake faces bending and twisting. Static illustrations and photos are perfectly cool too as well as citations with a different voice. In my opinion those only distract and carry no additional value.

I think the animation was okay, but you should include an animation of yourself talking to one of the other generations. ;-) question/answer moment?

i found the animations creepy in the movements

Lovely touch with animation, in theory. I genuinely enjoyed it though

I liked them!

The animation was AWESOME !!!

A little spooky: Did C. W. Musser actually speak or write those words, or are you putting them in his mouth?

I like the creepy reanimation

The animations were great. Will your 3d program animate, if so maybe running them side by side will help with context.

the animations were jarring

😂 very amusing.

Sorry, I didn't like the animation but what I'm really sorry about is myself. You do such a great job with my education and I've never thanked you for it. Please continue to enlighten me with any of your musings.

ha! I think I might have found my answer... I always wanted a travel rig for my astro gear that I can print/make myself to fit the scopes I got ... I guess super glue treatment of the cogs and rings would increase their longevity and stress resilience. how about backlash? any to be found in an obvious manner?

Love your videos Robert.😁

Excellent idea I didn't fully understand until watching this. The narrative animations were very distracting however - would be much better off with only a static picture of whoever the quote is by.

😂 The animations are terrifying but fun 👍

love the videos, animation's however were a bit distracting and creepy... keep up the awesome videos tho i love ur content!

Ai animation on historical figures is… unsettling. The focus is all over the place.

Nice Vid Dude!

What's a good 3D printable design for a very thin approximately 10- to 20-fold reduction gearbox? High torque capable, slow, like sub 1rpm output. Backlash is permissible but drive smoothness and linearity must be high.

I have a serious question, but first… I’m fine with the animations, ability to improve animations will always be progressing! Hat said, AI is a very polarizing topic at the moment… and likely will for a few years. The QUESTION: Could the gear spline be done in reverse? I’m thinking may be useful say with the ‘clock mechanism’’, but instead of a mechanical capacitor… be used as a mechanical battery. (Video 2088) My idea.. maybe a couple of these (split ring harmonic gear sets) to allow that (from 2088 vid) to lower very slowly,but then spin an output shaft much faster. Then pull the “heavy” Sid back up to the starting position, with a small motor or by hand. (IF SO… then would that be useful in a form of gravity generator)?

The animations were creepy. Sorry mate! You gave a good presentation, though, as usual. Thank you!

Yep, no need for the Ai. I'm not fond of it and we are here to see YOU...

CCW/CW is very interresting by wave travel.

welcome to uncanny valley :)

Creeeeeepy AI... 😨

Antimation was better than the real dude who was disturbing. He didn’t know where to look and the eyes seemed to be of divergent directions

Extremely interesting! Great video on this complex gear, just some feedback; I really disliked the robot voice and talking photos. It made me uncomfortable in an uncanny valley way, if that makes sense. But other than that I was fascinated about the video

Great piece of info ,as always, not keen on the animation mate👍🏼🇦🇺

OMG its a SCP case file crossover😮

😃👍

Robert you do whatever you want to do with your videos. Me telling you I don't like an aspect of your video feels like a student telling a teacher that they don't like the trim around the blackboard. Loved the video! Fascinating how many possibilities there are for gears. Each one must feel like a eureka moment upon discovery. As they should :D Thank you for taking the time to share this knowledge. Hey did you see Tom Stanton made a 3D printed hand crank generator?¿ Worth a watch, right up your alley 😊

Stick some magnets on it you’ve got magnetic switching using the gears

The thing that drives me to watch your tech videos more than your competitors' is the child-like delight you exhibit when something works. Get your AI people to mimic your joyful personality and I'm sure they'll be a hit.

Great video! And I thought the animations were great 👍. But like any video animation it is important to not over do it :-)

Hi Robert, Love the videos, but not a fan of the creepy talking portraits... Everything else, great as always! Keep it up :)

I need this for a multi wimsthurstmachine and so im repeating history

i like the inventors speaking about their own nventions, it adds a connection there, it was stark at first with cheap ai but if you used a better ai engine i'm sure the effect would be better, regardless i'd suggest adding the name of the inventor onscreen too

Robert Trav here you need to make the bearded guy at 2. 02 seconds bug out and be a bit blood shot a bit just to mess with folks humor in fun .i played with ai art app i ant got the pittance in mind for it lol

Can the harmonic drive be back driven for a low torque, high speed? Is there a tutorial on how to design our own in tinkercad?

Looks familiar 🙂

You get the same compact high gear ratio, but you loose the zero backlash advantage.

What's the backlash like compared to a normal harmonic drive? I was looking at these for a 4th axis for my CNC but you can never trust chinese imports lol The AI animation was funny and unexpected

one maybe two animations per video, lest they are more of a distraction then a helping tool. And short ones at that

Keep doing the animation, it's a useful tool for teaching

The animations were just plain creepy. You are already animated enough, so, simmer down some!

i think the animations were neat and ai will only get better over time may as well use em

I would have preferred the voice on the animations to be Elvis', but hey.

I'm glad you tried out the animations, it's neat to see where the technology is at, but I would vote No. They are a little creepy.

Love the video on the harmonic gear. ABSOLUTELY HATE the ai animation and voice.

Really interesting video. Animations are a little disturbing.

Animation is spot on😊

I love your videos, but that animation was really distracting. I would rather hear you speak.
